I own you an apology! If I leave mml-generate-mime untouched, that is I neither use my modification nor do I use use Lars new code, but I use your *new* code then the generated and sent message is displayed *correctly* in thunderbird. The resulting message contains Content-type: multipart/alternative; boundary="=-=-=" Instead of Content-type: multipart/related; boundary="=-=-=" As it would in my case, but it seems that thunderbird is OK with that. The reason I wrote you earlier that your changes made things worse was that I did make a mistake in my modification of mml-generate-mime. I also thought I checked your code with the old mml function but for some reason the old version was not used even after a restart. Sorry for the trouble! Uwe
